The flexibility of the wire rope is improved by not rotating the wire rope
2024-10-24
An important feature of the non-rotating wire rope is to improve the flexibility of the wire rope, become soft, the recoil force is small, will not form kinks, and improve the non-rotating performance. Therefore, the non-rotating wire rope is also easy to install, safe and reliable to use, even in the case of stress, smooth operation is not easy to break the line. Even if the wire is broken, it will not tilt, still lie in the original position, will not scratch the rope wheel or drum, and will not affect the normal work of other wires. No rotating wire rope working principle The outer layer is wound in the opposite direction. When the outer layer is subjected to the opposite direction of the force, the torsion direction of the inner strand is opposite to the torsion direction of the outer strand, which will limit the rotating force of the outer strand, thus appropriately reducing the rotation Angle of the load-bearing object in the air. However, when the free end of the wire rope is opposite to the direction of rotation of the outer strand, the inner strand will be pulled tight, making the inner strand shorter and the outer strand longer. But the ends of the rope are already tight, which will force the outer strand to bulge, causing the inner and outer strands to separate. In order to prevent the separation of the inner and outer strands, the reason for the equal torque of the inner and outer strands should be considered in the design and production. 1. The inner and outer layers should twist in different directions. 2. The structural diameter of the strands in each layer can be the same or different, but the strands in the same layer should be the same. 3. If the wire rope is made of steel wire of different diameters, a thicker one should be selected as the outer strand to increase the wear resistance and stiffness of the outer strand. 4. Twisting parameters are calculated according to the balance conditions of the sum of the inner and outer strands, but in order to prevent delamination, the twist distance of the inner strands can be appropriately reduced by about 15%-20% to increase the torque of the inner strands. 5. Change round stock to special-shaped stock to increase the supporting area of wire rope, reel and pulley. |
